COMBINED TYPE-WRITING AND COMPUTING MACHINE.

Specification of Letters Patent.

Patented Jan. 30, 1917.

Application flied February-17, 1912. Serial No. 678,299.

To all whom it may concern bers.

In the combined typewriting and com uting machine known as the Underwoodanson, a dog upon the paper carriage of the typewriter is employed forliftingone after another certainbars, each of which has a complement of computation pins; and this lifting of any bar brings all the pins thereon into position to be set by the keys.

The principal object of the invention is to provide simple, inexpensive, reliable, and easily operated means readily applicable to existing machines for enabling the keys to perform the function of lifting said pin bars so as to relieve the carriage from this work.

According to the present improvements, a universal lifter for the computation pin bars is actuated at every stroke of each numeral key; and the letter-feeding carriage of the machine determines which of said computation bars shall be lifted by the key; or in other words, said carriage selects the denomination of the computation pin which is to be set by any key at-any point in the column of figures.

There is employed the usual dog upon the carriage which operates serz'atim the usual denominational jacks upon the machine frame; and links connect these jacks to a nest of linkages, whereby the order of operation is reversed, so that when the'extreine right-hand jack is displaced by said carriage dog. the extreme left-hand linkage is actuated. Each of these linkages is adapted to effect a connection between its associated computation-pin bar and said universal lifter, so that the operation of the latter (which occurs during the key stroke) causes the selected pin-bar to be elevated, and

hence the key which is beingdepressed may set a pin on said elevated bar. Other ,features and advantages will herematter appear. In the accompanying drawings, Figure is a sectional elevation from front to rear ofa n Underwood-Hanson combined typewriting and computing machine, embodying the present improvements. Fig. 2 is a plan of the carriage dog and the computation jacks operable thereby. Fig. 3 is a view similar to the lower portion of Fig. 1, but showing a numeral key depressed. Fig. 4 1s a rear elevation of a' nestof transposition linkages. Fig. 5 is a perspective view of one of the linkages seen at Fig. 4, and the device whereby it connects its associated computation-Din bar with the universal lifter for the pin bars.

Alphabet keys 1 and numeral keys 2, provided upon the forward ends of levers 3, are operated to rock bell cranks 4 to swing type bars 5 up against a platen 6. The laten is mounted upon a carriage 7, which 1s propelled by a spring barrel 8 and controlled in the usual manner by an escape ment wheel 9 and dogs 10, the latter operated by a universal bar 11, which is driven by heels 12 on the type bars. Dial wheels 13 are operated by pinions 14, which mesh with racks 15 formed upon bars 16, one for each dial wheel; each bar-carrying a set of computation pins 17, which are depressible by linkages 18, the latter including rock shafts 19 which have the usualarms 20 engage-able by stems 21 pendent from the numeral keys 2. The depression of any numeral key 2 to operate its type bar causes the depression of the corresponding linkage 18, whereby one of the pins 17 is depressed in the path of a bar 22 on a general operator 23, which is operated by a crank 2% after all of the desired pins 17 have been set. The crank is fixed upon a rock shaft 25; and the shaft carries a gear 26, which meshes with an idle pinion 27, the latter meshing with the rack 23 and forming part of the general operator for the computing wheels. The pins 17 therefore form'part of an indexing mechanism which determines how far the gen computing wheels. 1

In order to depress or setone of the pins end operator will driv 'the fill is returned 17, however, its bar 16 must be lifted above the other bars; and thls is done by a denomination-selecting mechamsm, which is controlled by the typewriter carriage in conjunction with the numeral keys Upon the stem 21 of each numeral key 2 is carried a pawl 28; and in 'thepaths of these pawls or projections a hQi'izontaluniversal bar 29 extends across the machine,

so as to be depressed upon the down stroke of any numeral key 2. This universal .bar is mounted upon arms 30 at opposite sides of the machine,- said arms pivoted to the framework at 31 between the ends of the latter. Joining the rear ends of the arms 30 is a second universal bar 32, which rises when the universal bar 29 is depressed; and by means of said bar 32 anyone of a series of floating interponents in the form of hooks 33 maybe lifted, to raise the rear end of its associated pin-carrying bar 16. There is one hook for each of said bars 16; and they are mounted upon a transverse fixed rod 3ft. lt will be noted that hooks 3 33 in. addition to having a pivotal connection with the rod also have slots 33 whereby the hooks may be moved vertically relative to the bar 3% to raise the corre sponding pin bars 16.

Normally the hooks 33 are all held out of working positions by individual tension springs 35 I the typewriter progresses, the hooks 33 are swung forwardly one after another to catch under the computation bars 16;,the'se movements of the hooks being eiiected by linkages, each comprising a vertical linker bar 36 having a projection 37 to engage the hook and throw it beneath the adjacent bar 16. At each such motion of the hook about the pivot rod 34c, a catch 38 thereon swings over the universal bar 32, so that at the depression of the key 2, the hook 33 is carried up by said universal bar 32, thus liftv ing he associated 16, so that the pins 1'? thereon are above at e other pins in the nest, and so that h descending linkage 18 will depress or of the pins on said elevated bar. The work of lifting the bar and depressing the pins is all taken finger key, thus relieving the paper of work, and making more sensitive and Upon the relief oi carriage liter to run and n presure, it to pos c. usual s 'iring 39. The ilfQl'Stl har fr .0 is returned by a spri'i' g lO, and hook 30 returns to nor-- mal position under the inliiumcev of spring 3?, thus permitting the computation bar l6 to di pp. The hooks 33 also have springs l-l to pull them down to normal positions after,

actuation. The linkages comprising the bars 36 are returned by springs ments of the linkages 36 are effected by a dog carried by an arm 4% on the carriage the computing zone thereof,

but as the paper carriage 7 of by the of contact therewith 7, said dog lifting the forward ends 0' a series of jacks one after another; said jacks pivoted on a fixed rod 46 and the rear ends operating to depress links 47 whose lower ends are pivoted to cranks 48 on horizontal rock shafts 49. Each of these rock shafts 49 carries a crank 50 to engage a pin 51 in a link 52, which connects arms 53 and 54; of a pair of bell cranks. These bell cranks also comprise arms 55, 56, which are pivotally connectedby the bars or links 36.

At each motion of the paper carriage, in one of the jacks -15 is operated, and the corresponding link 4-? is thrust down and the rock shaft 49 is rocked, and linkages 52, 53, 55 and 36 are operated to thrust forwardly the hook 33 beneath the associated computation rack 16.

It will be seen at Fig. 4, which is a rear elevation, that the linkages 53, etc., form a transposition device, whereby the first operated jack is is connected to the computa tion bar 16 of highest denomination, the second jack to the bar of next lower denomination, and so on.

As, in some cases, move so promptly and to cause one of the hooks 33 to be swung about the pivot rod 34-, while the universal bar is still elevated, provision is preferably made for pivoting the latches 38 at 57, to the upper arm 58 of the book 33, so that the said univc bar 32 may swing any interfering latches one side and descend notwithstanding that another hook 33 is pressed forwardly by the projection 37; A spring 59 will snap the latch 38 over the universal bar 58 when the latter returns to normal position.

Variations may be resorted to within the scope of the invention, and portions of the imprm'emen-ts may be used without others.
